Stainless Steel 1.4848 vs CF8C

Stainless Steel · grade comparison

Stainless Steel 1.4848 and CF8C are both stainless steel grades. 1.4848 is the stronger of the two: yield strength 280 MPa (40.6 ksi) against 255 MPa (37 ksi) for CF8C, about 10% more. In exchange, CF8C is the more ductile: elongation 39% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 150 HB). 1.4848 runs hotter in service (1,100°C vs 816°C continuous) and CF8C conducts heat better (16.3 W/m·K vs 14 W/m·K). On the shop floor, CF8C machines more easily (fair vs poor) and CF8C welds better (excellent vs fair).

1.4848Choose it when strength drives the design, or when the part sees heat.

CF8CChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

1.4848 vs CF8C — frequently asked

Is 1.4848 stronger than CF8C?

Yes. 1.4848 has a typical yield strength of 280 MPa (40.6 ksi) against 255 MPa (37 ksi) for CF8C — about 10% more. Tensile strength is 530 MPa (76.9 ksi) vs 530 MPa (76.9 ksi).

Which is cheaper, 1.4848 or CF8C?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1.4848 or CF8C?

CF8C. Its machinability rates fair (40/100) against poor (25/100) for 1.4848; for welding the order is CF8C first (excellent, 85/100) then 1.4848 (fair, 45/100).
